i heard the bypass valve doesnt always keep the water out.i heard its not it also sucks in water not as much but it does.let me know if thats true.

The Bypass valve only works when the Filter is submerged. For example, a bucket of water with the filter all the way to the bottom.

So you're saying there's no point of putting the Bypass valve on??

Who would be dumb enough to drive through a flooded street w/ 5 inches of water?


that's why I stay with short ram. Ambient temperature of air while the vehicle is in motion is at the same whether the filter is to the ground or up next to the hood.

short ram or comptech icebox. hydrolock is the most annoying thing in the world to have to worry about. imagine every puddle in the rain being your enemy. yeah.

I'd stongly advocate either the Comptech Icebox, or a short ram intake. The risk of hydrolock - water ingestion- is simply too great IMO. Also, if you are considering going turbo, I'd recommend saving your money; the intake will be made redundant (or be physically incompatible) with the turbo kit.

I have an AEM, it works just fine for me. No complaints. Get a bypass valve. Mine came in handy last week when I hit an unexpected puddle in the middle of the road.

you didnt see the review that the designer was involved in.... i cant remember which mag did it (super street or SCC) and nobody was willing to test it on their car so the guy from AEM that designed it put his nsx on a dyno and they made an extension for his intake, submerged it in 18" of water.... you could see in the pics all the water gettin sucked up into the pipe (they used a clear pipe) but nothing ruined the nsx... i was convinced.

if it aint turbo, theyre all the same bullshit

I'd say the vast quantities of people running around with AEM CAIs and the relatively nonexistant amount of people with hydrolocked engines is plenty of evidence that it's not a big deal. It's not like if you drive in the rain, or through a puddle, or whatever, you're going to kill your motor. A little water ain't gonna hurt it, because it evaporates pretty much as soon as it hits the motor.

Hyrdolock is caused because liquids are not compressible like gasses are. To cause damage through hydrolock you need to get enough liquid in one cylinder to fill up its combustion chamber. An LS head's combustion chambers are 45 cc, or about an ounce and a half. Basically up to this point you will create higher and higher cylinder pressures which may or may not break something. If you get more water inside a cylinder than the volume of its combustion chamber, the engine will stop. When this happens, something breaks: a rod, piston, whatever.

Now to put that in perspective, that means the engine would need to suck enough water through the filter, up that long pipe, to fill one cylinder with over 45 cc of water. That won't gonna happen from driving over some puddles or in the rain.

most peoples has AEM CAI, or you can try the AEM V2 CAI.
